【Abstract】 The experimental research on the crystallization process of gas hydrate HCFC141b is performed in this paper. The influences of different proportions of calcium hypochlorite or benzenesulfonic acid sodium salt on the crystallization process are studied. The results show that the degree of subcooling of formation decreases obviously, and the formation rate of gas hydrate is greatly accelerated by adding reasonable proportions of the additives. The degree of subcooling of formation decreases 0.78℃ by adding benzenesulfonic acid sodium salt of 0.03%, and the formation rate of gas hydrate increases 0.2 g/s by adding calcium hypochlorite of 0.08%. In the cool storage system, clathrate hydrates can be formed effectively and thermal energy can be stored efficiently. When adding benzenesulfonic acid sodium salt of 0.03%, the cold energy stored is 4.74 MJ and the cool storage density is 206.07 MJ/m 3. The performance of this cool storage system can meet the needs of the practical air conditioning engineering.更多还原
